Flashboost Boat Calculator

Calculates the boat distances between flashes - allowing both no-run no-jump and macro boosts to work correctly. Distances are not 100% accurate but will give you the best possible calculation.

💡 How to use: Take your player entity + boat and press CTRL + M to open the transform window. Select "Move". The "Landing Spot" XYZ - those are your input values. Remember to move your new boat's position down {z units} to place your boat in the perfect position!

1. Angle Vector Conversion

Formula

DEG2RAD = π / 180

Forward Vector:
  X = cos(pitch) × cos(yaw)
  Y = cos(pitch) × sin(yaw)
  Z = -sin(pitch)

Right Vector:
  X = -sin(roll) × sin(pitch) × cos(yaw) + cos(roll) × sin(yaw)
  Y = -sin(roll) × sin(pitch) × sin(yaw) - cos(roll) × cos(yaw)
  Z = -sin(roll) × cos(pitch)

Example: 35° Boost Angle

                        Input: pitch = -35°, yaw = 0°, roll = 0°

                        Converted: pitch = -0.6109 rad

                        Forward = [0.8192, 0.0000, 0.5736]

                        Right = [0.0000, -1.0000, 0.0000]

2. Grenade Velocity Calculation

Throw Angle Adjustment

throwAngle = -10.0 + (-angle) + |(-angle)| × 10.0 / 90.0

Throw Velocity

ThrowVelocity = (90.0 - throwAngle) × 6.0
Max velocity clamped at 750 u/s

If Macro: PlayerVelocity.Z = 290.0
Else: PlayerVelocity.Z = 0.0

GrenadeVelocity = forwardVector × ThrowVelocity + PlayerVelocity

Example: 250 u/s Booster, 35° Angle, Macro

                        throwAngle = -10 + 35 + 35×(10/90) = 28.889°

                        ThrowVelocity = (90 - 28.889) × 6 = 366.67 u/s

                        PlayerVelocity = [204.8, 0, 290.0] (macro boost)

                        GrenadeVelocity = [504.8, 0, 500.3]

3. Player Boost Velocity

Impulse Formula

impulse = grenadeVelocity × 0.135

velocity.X = PlayerVelocity.X - grenadeVelocity.X
velocity.Y = PlayerVelocity.Y - grenadeVelocity.Y
velocity.Z = grenadeVelocity.Z

velocity.X += impulse.X
velocity.Y += impulse.Y

Clamp horizontal speed to max 3500 u/s

Example: Flyer at 250 u/s, Grenade [504.8, 0, 500.3]

                        impulse = [68.15, 0, -67.54]

                        velocity = [-250 - 504.8 + 68.15, 0, 500.3]

                        velocity = [-686.65, 0, 500.3]

                        Final horizontal speed = 686.65 u/s

4. Landing Position Calculation

Projectile Motion with Gravity

gravity = 800 units/s² (Source engine default)
tickInterval = 0.01s (100 tick server)

For each tick:
  newZ = velocity.Z - (gravity × 0.5 × tickInterval × 2)
  avgZ = (velocity.Z + newZ) / 2

  position.X += velocity.X × tickInterval
  position.Y += velocity.Y × tickInterval
  position.Z += avgZ × tickInterval

  velocity.Z = newZ

Stop when: newZ ≤ 0 AND position.Z ≤ landHeight

Linear Interpolation for Precision

fraction = (landHeight - startZ) / (endZ - startZ)

finalX = startX + (endX - startX) × fraction
finalY = startY + (endY - startY) × fraction
finalZ = landHeight

Example: Velocity [-686.65, 0, 500.3], Landing at 72 units

                        Start position: [0, 0, 72]

                        Simulate ~120 ticks until landing

                        Peak height: ~176 units (at tick 62)

                        Landing offset: [-823.5, 0, 72]

                        Boat placement: X = -823.5, Y = 0, Z = 0

                        (Z reduced by 72 units for player origin)

5. Yaw Angle Application

Vector Rotation

speed = √(velocity.X² + velocity.Y²)

velocity.X = cos(yawAngle) × speed
velocity.Y = sin(yawAngle) × speed

Example: 686.65 u/s at 90° (East)

                        yaw = 90° = π/2 radians

                        cos(90°) = 0, sin(90°) = 1

                        velocity.X = 0 × 686.65 = 0

                        velocity.Y = 1 × 686.65 = 686.65

                        Player travels purely East

Conclusion

In the short of it. Magic fucking math.

While not 100% accurate due to engine quirks, this calculator provides the most reliable boat placement coordinates available for trikz mapping.
